The horse (Equus caballus sometimes seen as a subspecies of the Wild Horse, Equus ferus caballus) is a large odd-toed ungulate mammal, one of ten modern species of the genus Equus. Horses have long been one of the most economically important domesticated animals, and have played an important role in the transport of people and cargo for thousands of years. While isolated domestication may have occurred as early as 10,000 years ago, clear evidence of widespread horse use by humans dates to around 2000 BC. Since they were domesticated, selective breeding has resulted in many breeds. Some have been bred so that they can be ridden, usually with a saddle, while other breeds can be harnessed to pull objects like carriages or plows. In some cultures, horses are a source of food, including horse meat and sometimes milk; in other cultures it is taboo to eat them. Today, in wealthy countries, horses are predominantly kept for leisure and sporting pursuits, while they are still used as working horses in many other parts of the world.http://www.feetandfins.com/horses/http://www.esyndicat.com/
